Thanks for doing this! inboard is typically < 40% efficient due to small prop which offers huge room for improvement. Its like retrofitting a powerboat with sails to spin the same shaft. I achieve 3 knots at 300 watts with no sails up on my 33ft boat using a $100 ebike hub motor spinning 32 inch carbon prop. You could double the efficiency of this setup, cut motor, battery, solar, cost and weight in half and have the same range and performance.

@@charonstyxferryman All valid points from Sean, Dave, Lars: 1. A larger prop will be more efficient, but it's also more of a risk for damage, especially if plastic, and if it doesn't feather will cause more drag under sail (without regen). 2. A smaller, feathering, metal prop won't be as efficient, but will be more resistant to damage, and will be more efficient when under sail only. All things engineering are tradeoffs of different kinds. For local sailing a larger plastic prop may be ok. For world cruising, a more conventional prop is probably better due to being more reliable, if less efficient. Since most sailboats spend more time sailing than motoring, a feathering prop is probably more efficient overall in terms of drag, time, speed, etc.

Such a great project. I saw on the specs that you have 350 amps storage, and the draw is 12-amps at 3-knots. 350 amps / 12-amps per hour =~ 29-hours 29-hours x 3-knots per hour = ~ 87-nautical miles Are my calculations incorrect?

@dave80399
@dave80399 Жыл бұрын
You'll need to know your consumption. So for example with no sun I find that I'm drawing about 30 amps to go 4kts. My battery monitor tells me that via shunting power and providing a reading. You won't be able to calculate what you'll use per speed accurately without testing and monitoring because there are so many variables like water length, keel type, conditions, motor consumption and efficiency etc. The renogy battery monitor and shunt will do it for you and it's only $75

In fact, I could probably generate around 4 kW of solar power. Thanks again, Glenn

After two years I'm super happy with the setup. I would do a few things differently. 1-i would reduce my battery capacity. I've never run below 50%. 2-I would remove my auxiliary/backup battery. Never used it. One other thing is I would maybe add a 12v fan and vent to better cool the motor. I did have the motor temp sensor shut down the motor once because I ran it really hot pushing about 100xmps for a couple of hours on a hot day.

A couple of comments. 1. I wonder about the "kill switch" you installed. Looking at the specs for that type of switch I see that they are generally rated for 48V DC maximum, not 48VDC nominal. Your battery will operate above 48VDC, so you are above the voltage rating for the switch. Yes I am aware that some of the Chinese knock off switches claim 60 and even 72VDC rarings, but I question those ratings given that the quality switches (Blue Seas) are only rated for 48 VDC. Just something for you to check into. 2. The ABYC (American Boat and Yacht Council which establishes standards for boat systems has just recently issued a new standard for Lithium Iron Phosphate battery installs (standard E-13). Since the batteries and all components in the battery system are required to be UL listed (or meet equivalent european or SAE standards to meet the ABYC standard, I am sure your home built battery does not comply with the standard. Yes the ABYC standards are "voluntary", but most insurance companies view them as mandatory. You need to check with your insurer to see if your battery install needs to meet the new ABYC standard. If your insurer requires it to meet the ABYC standard your install may void your insurance should you have a claim. Just an other thing to check on. There are batteries that meet the ABYC requirements, but they are EXPENSIVE. As far as a bigger/different prop goes, you will be limited by prop tip clearance requirements (typically 10% of prop diameter). That will limit how big a prop you can install. In addition maximum prop rotation speed is limited by the speed at which cavitation occurs. You likely want to keep your prop speed below 1,500 rpm. Maximum prop rpm depends on prop diameter and depth of the prop. Going to a new prop (different diameter, disc area ratio, diameter and possible blade count) will require prop calculations specific to your boat and engine. The calculations are not complex, but they do take some time to program and you will need a bit of information about your hull (displacement, wetted surface area, LWL, LWB, etc.). Ideally you want your prop to be able to handle about 90-95% of engine power at the prop's maximum RPM.

If/when it needs to be rebuilt electric definitely is the replacement. Are you able to recoop power under sail? I know others all say that 6knots is about where they see good power recovery under sail. Which case your boat and mine only hit 6 knots going down hill with a hurricane pushing it😆

Thank you for making this and looks a great improvement. Just one suggestion, the fittings you have used o mount the panels to the stainless steel tube have a small grub screw to hold the tube. After two years I have noticed that some of mine are loose. I am also concerned how they will hold in a real blow, therefore have drilled, tapped and added a cap screw to each one. Drilling stainless is daunting, but firm pressure, a drop of oil and taking time worked well even with a battery drill. Adding thread locker to the cap screws means they are not coming out and the frame come apart at the wrong moment.

Cool setup. Does the 660W, 60V solar imply you can get (ideally) 10-11A of current from the solar for charging, motoring etc? Given the available solar peaks during the day, how long does it take to recharge from a 30% discharge (assuming 10h @ 3kt) on solar? Curious and trying not to ask a dumb question.
@dave80399
@dave80399 2 жыл бұрын
So I have 350 amp hour capacity so charging at 20 amps would take me about 5 hours if I was down 30%. I rarely get below 92% on the battery monitor though because I mostly sail and while sailing I am using solar and prop regen as I am moving. I never plug in my fast charger because a day at the slip has me fully recharged. Now when i do more of my longer cruising this will be more of a challenge, however I still never spend a day motoring. I only cruise when the conditions allow me to mostly sail or motor sail. that is a main requirement of going electric in my opinion. Motoring 2-3 days straight into the wind is not really appropriate for electric.

Hey John I'm from Ontario originally too (Windsor). Everything cost me about $6000 including the battery and motor set.

Hello, Your conversion looked very professional. Was that a kit or did you design that yourself? I have noticed a lot of cruisers converting to some kind of electric drive system. Do you know if the costs are similar? Btw what was the cost of the system that you installed? And is the motor you used AC or DC? Thanks

I designed some of it but the motor and controller came from thunderstruck. 10 kw, 48v DC. I built my own battery for about $2100 and the motor and controller were about $3000. With solar panels, instruments, aluminum parts it was about another additional $1000.

Thanks for a great overview. Documents like this seem simple, but help give folks a GREAT head start on doing their own conversions. Looks like you work in the space industry. I can tell from the Kapton tape. :) For info, the thing you're calling a contact is called a contactor. It's essentially a big power relay in a sealed container with arc quenching gas usually. The motor is so quiet. Would probably be even quieter with a different prop. Don't know if you answered it already, but what brand of cell did you get, and from which supplier? Would you recommend them again?

Thanks! Yes I know about the relay.....I always call it a contact LOL. I do work in the space industry....good catch! The battery cells I bought came from 2 vendors: Wullils (recommend) and Varicore (don't recommend). Thanks so much for watching!

Thanks for sharing, nice clean install. Showing your 'real-world' power usage helps, hoping you can also show power draw with a 20+ knot head wind when you get a chance. I'm babying my 40 year old yanmar for now as it's running good (original to my 1982 28' Albin Cumulus) but definitely lining up a similar install next year , I'm thinking for my sailing style 48v, 200ah should do, usage will be in and our of marina with portable generator as backup for the occasional short coastal sailing as needed. One question, would you still go with your battery cell approach or instead get 12v or 24v batteries and connect in series/parallel for 48v given current price points?

power consumption increases in a strong head wind. I have seen it increase by as much as 30%. I typically don't spend long periods motoring into the wind though. For that I would prefer diesel.

Hey Dave, great to see the video. Chris Smith here, we've compared a few notes in the facebook group. It looks like you're doing a little better than me with performance. I don't get 3 knots from 8 amps on my Pearson 28. I suspect my prop is not optimized. What are you using for a prop? Did you change it, or stick with what you had before? I didn't realize you were an EE. I would have asked you more questions! ;) I've still got some more updates to do after we haul out for the season up here in New England. Maybe I'll hit you up then.

Hey thanks so much! I kept my original 2-blade prop. my performance is highly dependent on conditions but i notice that I need to double amperage for every knot of speed roughly.

@@dave80399 yeah, I totally concur about the conditions. I had to run at 50-60A one day last week to make 2 knots into a 15-20 knot headwind as we came back into port. I think the tide was going out at the same time. I was glad we weren't too far out.

What is your top speed? For instance when running through a channel with traffic. Will it fight an outbound tide when returning to port? Also those that don't like the eclectic are probably not die hard sailors and like to run the engine a lot. Electric is just for maneuvering in and out of port and occasional low wind conditions. It's a very different experience than some are expecting.

I have gone over 6kts but it draws high current so prefer to keep it around 5. My diesel only ever got me up to 5 max. Yes true sailors don't need to motor much!

Love the content and your videos. So please don't get mad when I say this. When you explain stuff and speak while recording yourself, you say "uhh & uhm" a lot, almost every 3rd-5th word. Don't know if it's a nervous tick or subconscious but it's the only thing I'd change about your content. Just watch this video and you'll notice what I'm saying. Hope you're having a great day. Keep up the amazing work!
